Expression

EC Number Organism Comment Expression
7.3.2.4 Medicago truncatula MtNRT1.3 is environmentally downregulated by the addition of NO3- to the roots down
7.3.2.4 Medicago truncatula MtNRT1.3 is environmentally upregulated by the absence of NO3-, not as a result of a systemic signalling of plant N status up

General Information

EC Number General Information Comment Organism
7.3.2.4 evolution the enzyme is a member of the NRT1 superfamily Medicago truncatula
7.3.2.4 additional information MtNRT1.3 is a dual-affinity NO3- transporter Medicago truncatula
7.3.2.4 physiological function nitrate transporter NRT1.3 is involved in the control of primary root growth and NO3- sensing acting in the response to N limitation, which increases the ability of the plant to acquire NO3- under N-limiting conditions Medicago truncatula
